[] There WERE some gaps! Did NOT run patch_hcorr.py (2) see what calibration looks like: amp in [0.995, 1.005] : good enough to proceed to the next step. tweak later phase in (-.5, .5) : good enough to proceed to the next step. tweak later rule of thumb: errors when underway: scale factor of 1.02 (i.e. 2%) gives 10cm/s alongtrack error phase error of 1deg gives 10cm crosstrack error (goal is 1cm/s) tail -20 cal/watertrk/adcpcal.out Number of edited points: 20 out of 21 amp = 1.0050 + 0.0015 (t - 190.9) phase = -0.28 + -0.1849 (t - 190.9) median mean std amplitude 1.0040 1.0050 0.0088 phase -0.1460 -0.2844 0.6835 nav - pc 1.5000 0.9000 2.7319 var 0.0010 0.0013 0.0011 min var 0.0010 0.0011 0.0010 delta-u -1.5250 -0.4880 3.5275 delta-v -0.0850 -0.1350 4.3687 No tweaks necessary yet.
